Pplato Basic Mathematics Quadratic Functions And Their Graphs
Subtract both sides by 2;Let x=0 in the equation, then solve for y The yintercept is ( 0, –2 ) Now we can plot the two points on the xy axis and connect them using a straight edge ruler to show the graph of the line Example 2 Graph the equation of the line using its intercepts This

Solving Quadratic Equations By Graphing Examples
If x = 5, y = 2(5) 6 = 4 We then note that the graph of (5, 4) also lies on the line To find solutions to an equation, as we have noted it is often easiest to first solve explicitly for y in terms of x Example 2 Graph x 2y = 4 Solution We first solve for y in terms of x to get We now select any two values of x to find the associatedY/2 > x − 2 Multiply both sides by 2 to eliminate the fraction y > 2x − 4 Now, because of the > sign, plot a dashed line of y = 2x − 4 Example 3 Solve the following inequality by graphing 2x – 3y ≥ 6 Solution The first isIt's about finding the slope of
